Before proceeding to a detail description of tliemachine, abrief outline of its mode of operation will be given in connection with Figari. The feed and gage rolls 15, 43, are normally close togetherv and are continuously driven. Justin the rear of the bite of the `rolls is a stationary splitting knife Lil. kJust in front of the biteof the rolls is the forward edgev of an actuator 121 which controls the dogs by which the gage Y-ioll is to be locked in automatically adjusted position. Farther in front of the bite V,of the rolls is one end of .a pivoted lever 151 which controls the locking and unlocking of the indicator. Normally the indicator is locked in position to indicate the thickness of the fcrwardend of the sole which has previously passed through the machine, and the locking dogs by which the upper or gage roll is to be locked in adjusted position are held in inoperative position. lffvhen, now, a blank is presented to thev machine it raises the lever 151 to un .lockthe indicator, moves the actuator 121 to release the locking dogs and raises the gage Vroll rihe raising of this roll turns the rindicator to expose to view the proper numeral, the released dogs lock the gage roll from movement, and the blank is split by passing through the machine. As the rear end of the blank passes from beneath the actuator 121 the dogs are once -more moved into inoperative'position but the indicator remainslocked until the next blank is presented to the machine andliftsvthe vforward end of the lever 151.

Referring now more particularlyA to Figs. 1, 2 and the shaft 13 of the lower or feed roll 15 is rotatably mounted in bearings carried at the ends of arms 17 which are pivoted about -the axis of studs 19 carried by the frame 21 of the machine. The bearings of this roll are normally held up against adjustable stop-screws .23 by round-headed pins the stems of which are received in sockets in cylindrical supports 27, said supports having at theirlower ends integral collars between which and the heads of the pins are located comparatively light coiled springs 29. Set screws 31 threaded through flanges on the frame furnish means yfor raising and lowering the supports 27 to vary the tension of the springs 29. The principal purpose of these light springs 29 is to hold the lower roll normally in the position shown, to permit it readily to be depressed when a blank is presented to the machine and to raise the roll if there occurs in the blank a spot so thin that otherwise the blank would not be properly fed.

Located in the rear of the i'oundheaded pins are round-headed pins 33 which are tireaded through cylindrical supports 35, said supports I being` vertically slidable through smooth bores in flanges of the frame 21. fleavy coiled springs 37 tend at all times to hold these supports las shown in their uppermost positions, such positions being determined by nuts 39 threaded upon the lower endsv of the supports 35. As has been stated, the light springs 29V normally.

hold the bearings ofthe lower roll up against the stop-screws 23.

In this position Q of parts the upper element of the roll is in In the present machine the rolls, and the amount it will be depressed before the upper or gage roll 43 is raised is determined by the positions of the roundheaded pins 33. ln order to permit simultaneous and equal vertical adjustment of these pins in their supports 35, there are slidably keyed on the lower ends of the stems of the pins gears 45, the stems having keyways 47 into which extend keys 49 which are fast to the gears. A rack-bar 51, horizontally slidable in the frame of the ma-` chine, meshes with these gears and may be moved in one direction or the other by ma.-V

nipulating the handle 53 of a bar 55 which dis pivoted at 57 to the frame of the machine and has a slot 59 to receive a pin 61 carried by the rack bar. In order to hold the bar in adjusted position and at the same time to permit it to be manipulated when desired, a spring-pressed detent 63 carried by the bar, engages a ratchet segment 65 carried by the frame of the machine. With this construction, swinging of the handle 53 in one direction or the other will rotate the gears t5 to raise or lower the headed ins 33 so as to vary' the space between t ieir heads and the spherical sockets with which these heads contact. The distance from the heads to the sockets determines the extent to which the lower roll will be depressed before the upper roll is raised and locked, as will presently be described. This distance also determines thev thickness of the skiving which will be removed from a blank of uniform thickness. If the blank has lof the 'forward end of aY blankfbetween the rolls depresses the lower-roll a slight dis-k 'tinck spots', the Sponges? wai yield sin Ianordinary splitting machine.

The bearings of the vupper roll are'formed 1in a forked casting 67 pivoted about a fixed rocl 69`and having atail providedjat its end with -a `spherical socket to Vreceive a -bu-tton 71. A similar Abuttonl y73 is located in a socket inthe frame ofthe machine; vand a coiled spring 75l-is located 'between the buttons, an; adjusting screw Z7 vfurnishing 'means lfor varying the tension of they spring.

This spring tends to rock the casting 67 about its `pivot, 69 in aj counter-clockwise fdirectio-n, as viewed in Fig. 1, to cause the upper roll i3 to approachlthe lower roll '15' and isli'mited in this movement by a'set screw 79 whichengages a lug on the meinber 67. This screw isset so that normally the upper rollis close to the flower-roll.

As has been explained above,-the entrance tance, determined by lthe positions of vthe headed pins r33, andraises the upper roll,

said upper Aroll being automatically *locked from f-urtlier bodily movement before Vthe -fo'iwvardiend'oflthe blanlrre'acl'ies the knife and remaining so vlocked kwhile the blank isbeing split. -Referring now more particulai-ly! to; Figs. 1, 5, 6- and 7', there is attached by a link 81 to thelowerend of thecasting 67, which carries the 'bearings-.in-wl'i-ic'h the slia'ft83 ofthe gagerolil" ismoun'ted', abell crank lever lSpii'fotedv :it-87 to the frame o-f` This lever at the endof Yits, horizontal arm -isprovided with a VslotV to receive a roll'89 on 'a pin- 90 which is driven into thelo'wer end of a toothedbar 91',.the

1 and 3, the casing 125 is fastened to the frame of the machine and carries a rotary shaft 127 to which the indicating wheel 129 is fast. yA pinion 131, fast to the shaft, meshes with a rack formed upon the upper endrof a rack bar 133 the lower end of which (see Fig. 1) rests upon the head of Y of a screw 135 threaded into the upper end V.and in effect part of the locking bar 91.

After the proper numeral has been exposed, 1t 1s desirable that 1t be heldin exposed position until the nextblank is presented to the machine so that the operator may notlose track of the measurement of the .sole whichis being or has been split. To this end a ratchet wheel 141, fast to the yshaft 127, is arranged to be engaged and locked by a pawl 143. This pawl is fast inside the casing 125 to the inner end of a small rock-shaft 145 which has a bearing in a boss on the side of the casins 125. At the outer end of the roch-shaft one end of an arm 147 is clamped, the other end Vhaving la downwardly facing spherical sockety to receive the rounded upper end of a rod 149. IThe lower end of this rod is also rounded and is received in a spherical socket at one end of a lever 151 which is pivoted at 153 to the frame Vof the machine. A tension spring 155 connects the arm 147 with the lever 151 and tends at all times to hold the rod 149 in its upper and lower sockets. The weight of that portion ofthe lever 151 which is to the left of the pivot 153, as viewed in Fig. 1, tends always to hold the parts in the positions shown with the pawl 143 in engagement with the ratchet- 141. As viewed in Fig. 9, the wheel may be turned in a connterclockwise direction but is held from turning in the opposite direction until the lever 151 is swung in a direction to release the pawl. The lever 151 extends toward the front of the machine through a groove in the lower roll 15 and is bent upwardly in front of the bite .of the rolls. As soon, therefore, as a blank is `fed over the table '153 to the machine, the forward end of the lever 151 is raised and the ratchet wheel 141 released, whereupon the spring 139 returns it tov normal position in which the numeral zero is exposed to view.

The rotation of the rolls 15 and 43 is controlled by tight and loose pulleys 157,

159 from one to the other of which a belt may be shifted by manipulating a handle 161 to reciprocate a slide rod 163 to one end of which the belt-engaginggmember 165 is attached. The pulleys are mountedon a drive shaft 167 having fast thereon a pinion 169 which meshes witha large gear 171 fast to the shaft 13.0f the vlower or feed roll. The left-hand end of this shaft, as viewedin Fig. 2, is connected by an Oldham coupling 173 with a vsmallgear 175 which is rotatable on a stub shaft carried by a rigid Vpart of the machine.. The gear 175 meshes with a gear 177 which is fast to the shaft of the upper roll. The table 153 at the front of the machine is provided with the usual upstanding side flanges 131.
